The present invention relates to compounds of the formula I

as inhibitors of the adhesion and migration of leucocytes and/or as antagonists of the adhesion receptor VLA-4 which belongs to the group of integrins. The invention relates to the use of compounds of the formula I and of pharmaceutical preparations which contain such compounds for the treatment or prophylaxis of diseases which are caused by an undesired extent of leucocyte adhesion and/or leucocyte migration of which are associated therewith or in which cell—cell or cell-matrix interactions which are based on interactions of VLA-4 receptors with their ligands play a part, for example of inflammatory processes, of rheumatoid arthritis or of allergic disorders, and it also relates to the use of compounds of the formula I for the production of pharmaceuticals for use in such diseases. It further relates to novel compounds of the formula I.

The integrins are a group of adhesion receptors which play an important part in cell—cell-binding and cell-extracellular matrix-binding processes. They have an αβ-heterodimeric structure and exhibit a wide cellular distribution and a high extent of evolutive conservation. The integrins include, for example, the fibrinogen receptor on platelets, which interacts especially with the RGD sequence of fibrinogen, or the vitronectin receptor on osteoclasts, which interacts especially with the RGD sequence of vitronectin or of osteopontin. The integrins are divided into three major groups, the β2 subfamily with the representatives LFA-1, Mac-1 and p150/95, which are responsible in particular for cell—cell interactions of the immune system, and the subfamilies β1 and β3, whose representatives mainly mediate cell adhesion to components of the extracellular matrix (Ruoslahti, Annu. Rev. Biochem. 1988, 57, 375). The integrins of the β1 subfamily, also called VLA proteins (very late (activation) antigen), include at least six receptors which interact specifically with fibronectin, collagen and/or laminin as ligands. Within the VLA family, the integrin VLA-4 (α4β1) is atypical in so far as it is mainly restricted to lymphoid and myeloid cells and is responsible in these for cell—cell interactions with a large number of other cells. For example, VLA-4 mediates the interaction of T and B lymphocytes with the heparin II-binding fragment of human plasma fibronectin (FN). The binding of VLA-4 with the heparin II-binding fragment of plasma fibronectin is especially based on an interaction with an LDVP sequence. In contrast to the fibrinogen or vitronectin receptor, VLA-4 is not a typical RGD-binding integrin (Kilger and Holzmann, J. Mol. Meth., 1995, 73, 347).

The leucocytes circulating in the blood normally exhibit only a low affinity for the vascular endothelial cells which line the blood vessels. Cytokines which are released from inflamed tissue cause the activation of endothelial cells and thus the expression of a large number of cell surface antigens. These include, for example, the adhesion molecules ELAM-1 (endothelial cell adhesion molecule-1; also designated as E-selectin), which, inter alia, binds neutrophils, ICAM-1 (intercellular adhesion molecule-1), which interacts with LFA-1 (leucocyte function-associated antigen 1) on leucocytes, and VCAM-1 (vascular cell adhesion molecule-1), which binds various leucocytes, inter alia lymphocytes (Osborn et al., Cell 1989, 59, 1203). VCAM-1, like ICAM-1, is a member of the immunoglobulin gene superfamily. VCAM-1 (first known as INCAM-110) was identified as an adhesion molecule which is induced on endothelial cells by inflammatory cytokines such as TNF and IL-1 and lipopolysaccharides (LPS). Elices et al. (Cell 1990, 60, 577) showed that VLA-4 and VCAM-1 form a receptor-ligand pair which mediates the adhesion of lymphocytes to activated endothelium. The binding of VCAM-1 to VLA-4 does not take place here due to an interaction of the VLA-4 with an RGD sequence; such one is not contained in VCAM-1 (Bergelson et al., Current Biology 1995, 5, 615). VLA-4, however, also occurs on other leucocytes, and the adhesion of leucocytes other than lymphocytes is also mediated via the VCAM-1/VLA-4 adhesion mechanism. VLA-4 thus represents an individual example of a β1 integrin receptor which, via the ligands VCAM-1 and fibronectin, plays an important part in cell—cell interactions and in cell-extracellular matrix interactions.

The cytokine-induced adhesion molecules play an important part in the recruitment of leucocytes into extravascular tissue regions. Leucocytes are recruited into inflammatory tissue regions by cell adhesion molecules which are expressed on the surface of endothelial cells and serve as ligands for leucocyte cell surface proteins or protein complexes (receptors) (the terms ligand and receptor can also be used vice versa). Leucocytes from the blood must first adhere to endothelial cells before they can migrate into the synovium. Since VCAM-1 binds to cells which carry the integrin VLA-4 (α4β1), such as eosinophils, T and B lymphocytes, monocytes or also neutrophils, it and the VCAM-1/VLA-4 mechanism have the function of recruiting cells of this type from the blood stream into areas of infection and inflammatory foci (Elices et al., Cell 1990, 60, 577; Osborn, Cell 1990, 62, 3; Issekutz et al., J. Exp. Med. 1996, 183, 2175).

The VCAM-1/VLA-4 adhesion mechanism has been connected with a number of physiological and pathological processes. Apart from cytokine-induced endothelium, VCAM-1 is additionally expressed, inter alia, by the following cells: myoblasts, lymphoid dendritic cells and tissue macrophages, rheumatoid synovium, cytokine-stimulated neural cells, parietal epithelial cells of the Bowman's capsule, the renal tubular epithelium, inflamed tissue during heart and kidney transplant rejection and by intestinal tissue in graft-versus-host disease. VCAM-1 is also found to be expressed on those tissue areas of the arterial endothelium which correspond to early arteriosclerotic plaques of a rabbit model. Additionally, VCAM-1 is expressed on follicular dendritic cells of human lymph nodes and is found on stroma cells of the bone marrow, for example in the mouse. The latter finding points to a function of VCAM-1 in B-cell development. Apart from cells of hematopoietic origin, VLA-4 is also found, for example, on melanoma cell lines, and the VCAM-1/VLA-4 adhesion mechanism is connected with the metastasis of such tumors (Rice et al., Science 1989, 246, 1303).

The main form in which VCAM-1 occurs in vivo on endothelial cells and which is the dominant form in vivo is designated as VCAM-7D and carries seven immunoglobulin domains. The domains 4,5 and 6 are similar in their amino acid sequences to the domains 1, 2 and 3. The fourth domain is removed in a further form, consisting of six domains, designated here as VCAM-6D, by alternative splicing. VCAM-6D can also bind VLA-4-expressing cells.

Further details on VLA-4, VCAM-1, integrins and adhesion proteins are found, for example, in the articles by Kilger and Holzmann, J. Mol. Meth. 1995, 73, 347; Elices, Cell Adhesion in Human Disease, Wiley, Chichester 1995, p. 79; Kuijpers, Springer Semin. Immunopathol. 1995, 16, 379.

On account of the role of the VCAM-1/VLA-4 mechanism in cell adhesion processes which are of importance, for example, in infections, inflammations or atherosclerosis, it has been attempted by means of interventions into these adhesion processes to control diseases, in particular, for example, inflammations (Osborn et al., Cell 1989, 59, 1203). A method of doing this is the use of monoclonal antibodies which are directed against VLA-4. Monoclonal antibodies (mAB) of this type which as VLA-4 antagonists block the interaction between VCAM-1 and VLA-4, are known. Thus, for example, the anti-VLA-4 mAB HP2/1 and HP1/3 inhibit the adhesion of VLA-4-expressing Ramos cells (B-cell-like cells) to human umbilical cord endothelial cells and to VCAM-1-transfected COS cells. The anti-VCAM-1 mAB 4B9 likewise inhibits the adhesion of Ramos cells, Jurkat cells (T-cell-like cells) and HL60 cells (granulocyte-like cells) to COS cells transfected with genetic constructs which cause VCAM-6D and VCAM-7D to be expressed. In vitro data with antibodies which are directed against the α4 subunit of VLA-4 show that the adhesion of lymphocytes to synovial endothelial cells is blocked, an adhesion which plays a part in rheumatoid arthritis (van Dinther-Janssen et al., J. Immunol. 1991, 147, 4207).

In vivo experiments have shown that an experimental autoimmune encephalomyelitis can be inhibited by anti-α4 mAB. The migration of leucocytes into an inflammatory focus is likewise blocked by a monoclonal antibody against the α4 chain of VLA-4. The influencing of the VLA-4-dependent adhesion mechanism by antibodies was also investigated in an asthma model in order to investigate the role of VLA-4 in the recruitment of leucocytes in inflamed lung tissue (U.S. Ser. No. 07/821,768; EP-A-626 861). The administration of anti-VLA-4 antibodies inhibited the late-phase reaction and respiratory tract overreaction in allergic sheep.

The VLA-4-dependent cell adhesion mechanism was also investigated in a primate model of inflammatory bowel disease (IBD). In this model, which corresponds to ulcerative colitis in man, the administration of anti-VLA-4 antibodies resulted in a significant reduction in the acute inflammation.

Moreover, it was possible to show that VLA-4-dependent cell adhesion plays a part in the following clinical conditions including the following chronic inflammatory processes: rheumatoid arthritis (Cronstein and Weismann, Arthritis Rheum. 1993, 36, 147; Elices et al., J. Clin. Invest. 1994, 93, 405), diabetes mellitus (Yang et al., Proc. Natl. Acad. Sci. USA 1993, 90, 10494), systemic lupus erythematosus (Takeuchi et al., J. Clin. Invest. 1993, 92, 3008), allergies of the delayed type (type IV allergy) (Elices et al., Clin. Exp. Rheumatol. 1993, 11, p.77), multiple sclerosis (Yednock et al., Nature 1992, 356, 63), malaria (Ockenhouse et al., J. Exp. Med. 1992, 176, 1183), arteriosclerosis (Obrien et al., J. Clin. Invest. 1993, 92, 945), transplantation (Isobe et al., Transplantation Proceedings 1994, 26, 867-868), various malignancies, for example melanoma (Renkonen et al., Am. J. Pathol. 1992, 140, 763), lymphoma (Freedman et al., Blood 1992, 79, 206) and others (Albelda et al., J. Cell Biol. 1991, 114, 1059).

VLA-4 blocking by suitable antagonists accordingly offers effective therapeutic possibilities, in particular, for example, of treating various inflammatory conditions including asthma and IBD. The particular relevance of VLA-4 antagonists for the treatment of rheumatoid arthritis in this respect results, as already stated. from the fact that leucocytes from the blood must first adhere to endothelial cells before they can migrate into the synovium, and that the VLA-4 receptor plays a part in this adhesion. The fact that VCAM-1 is induced by inflammatory agents on endothelial cells (Osborn, Cell 1990, 62, 3; Stoolman, Cell 1989, 56, 907), and the recruitment of various leucocytes into areas of infection and inflammatory foci has already been dealt with above. In this respect, T cells adhere to activated endothelium mainly via the LFA-1/ICAM-1 and VLA-4/VCAM-1 adhesion mechanisms (Springer, Cell 1994,76, 301). On most synovial T cells, the binding capacity of VLA-4 for VCAM-1 is increased in rheumatoid arthritis (Postigo et al., J. Clin. Invest. 1992, 89, 1445). Additionally, an increased adhesion of synovial T cells to fibronectin has been observed (Laffon et al., J. Clin. Invest. 1991, 88, 546; Morales-Ducret et al., J. Immunol. 1992, 149, 1424). VLA-4 is also upregulated both in the course of its expression and with respect to its function on T lymphocytes of the rheumatoid synovial membrane. The blocking of the binding of VLA-4 to its physiological ligands VCAM-1 and fibronectin makes possible an effective prevention or alleviation of articular inflammatory processes. This is also confirmed by experiments with the antibody HP2/1 on Lewis rats with adjuvant arthritis, in which an effective prevention of illness has been observed (Barbadillo et al., Springer Semin. Immunopathol. 1995, 16, 427). VLA-4 is thus an important therapeutic target molecule.

The abovementioned VLA-4 antibodies and the use of antibodies as VLA-4 antagonists are described in the Patent Applications WO-A-93/13798, WO-A-93/15764, WO-A-94/16094, WO-A-94/17828 and WO-A-95/19790. In the Patent Applications WO-A-94/15958, WO-A-95/15973, WO-A-96/00581, WO-A-96/06108 and WO-A-96/20216, peptide compounds are described as VLA-4 antagonists. The use of antibodies and peptide compounds as pharmaceuticals, however, is afflicted with disadvantages, for example lack of oral availability, easy degradability or immunogenic action on longer-term use, and there is thus a need for VLA-4 antagonists having a favorable profile of properties for use in therapy and prophylaxis.

WO-A-95/14008 describes substituted 5-membered ring heterocycles which have an amino, amidino or guanidino function at the N-terminal end of the molecule and which exhibit platelet aggregation-inhibiting activity. The German Patent Application 19635522.2 describes further heterocycles which are inhibitors of bone resorption. Indications that the compounds covered by the German Patent Application 19635522.2 are VLA-4 antagonists or inhibit leucocyte adhesion are not found there, however. Surprisingly, it has now been found that compounds covered by the German Patent Application 19635522.2 also inhibit leucocyte adhesion and are VLA-4 antagonists.

Alkyl radicals can be straight-chain or branched. This also applies if they carry substituents or occur as substituents of other radicals, for example in alkoxy, alkoxycarbonyl or aralkyl radicals. The same applies to alkylene radicals. Examples of suitable (C₁-C₂₈)-alkyl radicals are: methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, decyl, undecyl, dodecyl, tridecyl, pentadecyl, hexadecyl, heptadecyl, nonadecyl, eicosyl, docosyl, tricosyl, pentacosyl, hexacosyl, heptacosyl, octacosyl, isopropyl, isobutyl, isopentyl, neopentyl, isohexyl, 3-methylpentyl, 2,3,5-trimethylhexyl, sec-butyl, tert-butyl, tert-pentyl. Preferred alkyl radicals are methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl and tert-butyl. Examples of alkylene radicals are methylene, ethylene, tri-, tetra-, penta- and hexamethylene or methylene substituted by an alkyl radical, for example methylene which is substituted by a methyl group, an ethyl group, an isopropyl group, an isobutyl group or a tert-butyl group.

Alkenyl and alkenylene radicals as well as alkynyl radicals can also be straight-chain or branched. Examples of alkenyl radicals are vinyl, 1-propenyl, allyl, butenyl, 3-methyl-2-butenyl, examples of alkenylene radicals are vinylene or propenylene, and examples of alkynyl radicals are ethynyl, 1-propynyl or propargyl.

Cycloalkyl radicals are, in particular, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, cyclononyl, cyclodecyl, cycloundecyl and cyclododecyl, which, however, can also be substituted by, for example, (C₁-C₄)-alkyl. Examples of substituted cycloalkyl radicals which may be mentioned are 4-methylcyclohexyl and 2,3-dimethylcyclopentyl. The same applies to cycloalkylene radicals.

The 6- to 24-membered bicyclic and tricyclic radicals R¹⁶ are formally obtained by abstraction of a hydrogen atom from bicyclic systems or tricyclic systems. The bicyclic systems and tricyclic systems on which they are based can contain only carbon atoms as ring members, i.e. they can be bicycloalkanes or tricycloalkanes, but they can also contain one to four identical or different heteroatoms from the group consisting of nitrogen, oxygen and sulfur, i.e. they can be aza-, oxa- and thiabicyclo- and -tricycloalkanes. If heteroatoms are contained, preferably one or two heteroatoms, in particular nitrogen or oxygen atoms, are contained. The heteroatoms can assume any desired positions in the bi- or tricyclic structure; they can be located in the bridges, or in the case of nitrogen atoms, also at the bridgeheads. Both the bicyclo- and tricycloalkanes and their heterocyclic analogs can be completely saturated or can contain one or more double bonds. They preferably contain one or two double bonds or, in particular, are completely saturated. Both the bicyclo- and tricycloalkanes and the heterocyclic analogs and both the saturated and the unsaturated representatives can be unsubstituted or substituted in any desired suitable positions by one or more oxo groups and/or one or more identical or different (C₁-C₄)-alkyl groups, for example methyl or isopropyl groups, preferably methyl groups. The free bond of the bi- or tricyclic radical can be located in any desired position of the molecule; the radical can thus be bonded via a bridgehead atom or an atom in a bridge. The free bond can also be located in any desired stereochemical position, for example in an exo or an endo position.

Examples of parent structures of bicyclic ring systems from which a bicyclic radical can be derived are norbornane (=bicyclo[2.2.1]heptane), bicyclo[2.2.2]octane and bicyclo[3.2.1]octane, examples of unsaturated or substituted systems or systems containing heteroatoms are 7-azabicyclo[2.2.1]-heptane, bicyclo[2.2.2]oct-5-ene and camphor (=1,7,7-trimethyl-2-oxobicyclo[2.2.1]heptane).

Examples of systems from which a tricyclic radical can be derived are twistane (=tricyclo[4.4.0.0^(3.8)]decane), adamantane (=tricyclo[3.3.1.1^(3.7)]-decane), noradamantane (=tricyclo[3.3.1.0^(3.7)]nonane), tricyclo[2.2.1.0^(2.6)]-heptane, tricyclo[5.3.2.0^(4.9)]dodecane, tricyclo[5.4.0.0^(2.9)]undecane or tricyclo[5.5.1.0^(3.11)]tridecane.

Preferably, bicyclic or tricyclic radicals are derived from bridged bicyclic systems or tricyclic systems, i.e. from systems in which rings together have two or more than two atoms. Bicyclic or tricyclic radicals having 6 to 18 ring members are additionally preferred, particularly preferably those having 7 to 12 ring members.

Specifically particularly preferred bi- and tricyclic radicals are the 2-norbomyl radical, both that with the free bond in the exo position and also that with the free bond in the endo position, the 2-bicyclo[3.2.1]octyl radical, the 1-adamantyl radical, the 2-adamantyl radical and the noradamantyl radical, for example the 3-noradamantyl radical. The 1- and the 2-adamantyl radicals are moreover preferred.

(C₆-C₁₄)-aryl groups are, for example, phenyl, naphthyl, biphenylyl, anthryl or fluorenyl, where 1-naphthyl, 2-naphthyl and in particular phenyl are preferred. Aryl radicals, in particular phenyl radicals, can be mono- or polysubstituted, preferably mono-, di- or trisubstituted, by identical or different radicals from the group consisting of (C₁-C₈)-alkyl, in particular (C₁-C₄)-alkyl, (C₁-C₈)-alkoxy, in particular (C₁-C₄)-alkoxy, halogen, nitro, amino, trifluoromethyl, hydroxyl, methylenedioxy, ethylenedioxy, cyano, hydroxycarbonyl, aminocarbonyl, (C₁-C₄)-alkoxycarbonyl, phenyl, phenoxy, benzyl, benzyloxy, (R⁸O)₂P(O), (R⁸O)₂P(O)—O—, tetrazolyl. The same applies. for example, to radicals such as aralkyl or arylcarbonyl. Aralkyl radicals are, in particular, benzyl as well as 1- and 2-naphthylmethyl, 2-, 3- and 4-biphenylylmethyl and 9-fluorenylmethyl which can also be substituted. Substituted aralkyl radicals are, for example. benzyl and naphthylmethyl substituted in the aryl moiety by one or more (C₁-C₈)-alkyl radicals, in particular (C₁-C₄)-alkyl radicals, for example 2-, 3- and 4-methylbenzyl, 4-isobutylbenzyl, 4-tert-butylbenzyl, 4-octylbenzyl, 3,5-dimethylbenzyl, pentamethylbenzyl, 2-, 3-, 4-, 5-, 6-, 7- and 8-methyl-1-naphthylmethyl, 1-, 3-, 4-, 5-, 6-, 7- and 8-methyl-2-naphthylmethyl, or benzyl and naphthylmethyl substituted in the aryl moiety by one or more (C₁-C₈)-alkoxy radicals, in particular (C₁-C₄)-alkoxy radicals, for example 4-methoxybenzyl, 4-neopentyloxybenzyl, 3,5-dimethoxybenzyl, 3,4-methylenedioxybenzyl, 2,3,4-trimethoxybenzyl, further 2-, 3- and 4-nitrobenzyl, halobenzyl, for example 2-, 3- and 4-chloro- and 2-, 3- and 4-fluorobenzyl, 3,4-dichlorobenzyl, pentafluorobenzyl, trifluoromethylbenzyl, for example 3- and 4-trifluoromethylbenzyl or 3,5-bis(trifluoromethyl)benzyl. Substituted aralkyl radicals, however, can also have different substituents. Examples of pyridyl are 2-pyridyl, 3-pyridyl and 4-pyridyl.

In monosubstituted phenyl radicals, the substituent can be located in the 2-, the 3- or the 4-position, the 3- and the 4-positions being preferred. If phenyl is disubstituted, the substituents can be in the 1,2-, 1,3- or 1,4-position relative to one another. Disubstituted phenyl can thus be substituted in the 2,3-position, the 2,4-position, the 2,5-position, the 2,6-position, the 3,4-position or the 3,5-position, relative to the linkage site. Preferably, in disubstituted phenyl radicals the two substituents are arranged in the 3-position and the 4-position, relative to the linkage site. The same applies for phenylene radicals which, for example, can be present as 1,4-phenylene or as 1,3-phenylene.

Phenylene-(C₁-C₆)-alkyl is, in particular, phenylenemethyl (—C₆H₄—CH₂—) and phenyleneethyl, (C₁-C₆)-alkylenephenyl is, in particular, methylenephenyl (—CH₂—C₆H₄—). Phenylene-(C₂-C₆)-alkenyl is, in particular, phenyleneethenyl and phenylenepropenyl.

Heteroaryl is a mono- or polycyclic aromatic radical having 5 to 14 ring members, which contains 1 to 5 heteroatoms as ring members. Examples of heteroatoms are N, O and S. If several heteroatoms are contained, these can be identical or different. Heteroaryl radicals can also be mono- or polysubstituted, preferably mono-, di- or trisubstituted, by identical or different radicals from the group consisting of (C₁-C₈)-alkyl, in particular (C₁-C₄)-alkyl, (C₁-C₈)-alkoxy, in particular (C₁-C₄)-alkoxy, halogen, nitro, amino, trifluoromethyl, hydroxyl, methylenedioxy, cyano, hydroxylcarbonyl, aminocarbonyl, (C₁-C₄)-alkoxycarbonyl, phenyl, phenoxy, benzyl, benzyloxy, (R⁸O)₂P(O), (R⁸O)₂P(O)—O—, tetrazolyl. Preferably, heteroaryl is a mono- or bicyclic aromatic radical which contains 1, 2, 3 or 4, in particular 1 to 3, identical or different heteroatoms from the group consisting of N, O and S and which can be substituted by 1, 2, 3 or 4, in particular 1 to 3, identical or different substituents from the group consisting of (C₁-C₆)-alkyl, (C₁-C₆)-alkoxy, fluorine, chlorine, nitro, amino, trifluoromethyl, hydroxyl, (C₁-C₄)-alkoxycarbonyl, phenyl, phenoxy, benzyloxy and benzyl. Particularly preferably, heteroaryl is a mono- or bicyclic aromatic radical having 5 to 10 ring members, in particular a corresponding 5- to 6-membered monocyclic aromatic radical, which contains 1 to 3 heteroatoms from the group consisting of N, O and S and can be substituted by 1 to 2 substituents from the group consisting of (C₁-C₄)-alkyl, (C₁-C₄)-alkoxy, phenyl, phenoxy, benzyloxy and benzyl.

Het on the one hand includes aromatic heterocycles and thus also the groups representing heteroaryl insofar as these come under the definition of Het with respect to the number of ring members and heteroatoms. Additionally, however, Het also includes nonaromatic heterocycles which are completely saturated or which contain one or more double bonds in the ring system. Het can be substituted on nitrogen atoms and/or carbon atoms by one or more identical or different substituents, for example by (C₁-C₈)-alkyl, in particular (C₁-C₄)-alkyl, (C₃-C₁₂)-cycloalkyl, (C₃-C₁₂)-cycloalkyl-(C₁-C₈)-alkyl, optionally substituted (C₆-C₁₄)-aryl, (C₆-C₁₄)-aryl-(C₁-C₈)-alkyl optionally substituted in the aryl radical, heteroaryl, heteroaryl-(C₁-C₈)-alkyl, (C₁-C₈)-alkoxy, in particular (C₁-C₄)-alkoxy, optionally substituted phenoxy, benzyloxy, halogen, nitro, amino, (C₁-C₈)-alkylamino, di-((C₁-C₈)-alkyl)amino, trifluoromethyl, hydroxyl, methylenedioxy, ethylenedioxy, cyano, hydroxylcarbonyl, aminocarbonyl, (C₁-C₄)-alkoxycarbonyl and generally by ester groups, acyl groups, (R⁸O)₂P(O), (R⁸O)₂P(O)—O—, oxo, thioxo, where alkyl radicals can be monosubstituted or polysubstituted by fluorine.

Heterocycles which represent mono- or bicyclic 5- to 12-membered heterocyclic rings can be aromatic or partially or completely saturated and can be substituted, in particular on a nitrogen atom, by (C₁-C₇)-alkyl, for example methyl or ethyl, phenyl or phenyl-(C₁-C₄)-alkyl, for example benzyl, and/or on one or more carbon atoms by (C₁-C₄)-alkyl, halogen, hydroxyl, (C₁-C₄)-alkoxy, for example methoxy, phenyl-(C₁-C₄)-alkoxy, for example benzyloxy, or oxo.

Examples of heterocycles on which the groups heteroaryl, Het or the mono- or bicyclic 5- to 12-membered heterocyclic ring can be based are pyrrole, furan, thiophene, imidazole, pyrazole, oxazole, isoxazole, thiazole, isothiazole, tetrazole, pyridine, pyrazine, pyrimidine, indole, isoindole, indazole, phthalazine, quinoline, isoquinoline, quinoxaline, quinazoline, cinnoline, β-carboline or benzo-fused, cyclopenta-, cyclohexa- or cyclohepta-fused derivatives of these heterocycles. Nitrogen heterocycles can also be present as N-oxides.

Radicals which can represent heteroaryl, Het or the radical of a mono- or bicyclic 5- to 12-membered heterocyclic ring are, for example, 2- or 3-pyrrolyl, phenylpyrrolyl, for example 4- or 5-phenyl-2-pyrrolyl, 2-furyl, 2-thienyl, 4-imidazolyl, methylimidazolyl, for example 1-methyl-2-, 4- or -5-imidazolyl, 1,3-thiazol-2-yl, 2-pyridyl, 3-pyridyl, 4-pyridyl, 2-, 3- or 4-pyridyl-N-oxide, 2-pyrazinyl, 2-, 4- or 5-pyrimidinyl, 2-, 3- or 5-indolyl, substituted 2-indolyl, for example 1-methyl-, 5-methyl-, 5-methoxy-, 5-benzyloxy-, 5-chloro or 4,5-dimethyl-2-indolyl, 1-benzyl-2- or -3-indolyl, 4,5,6,7-tetrahydro-2-indolyl, cyclohepta[b]-5-pyrrolyl, 2-, 3- or 4-quinolyl, 1-, 3- or 4-isoquinolyl, 1-oxo-1,2-dihydro-3-isoquinolyl, quinoxalinyl, 2-benzofuranyl, 2-benzothienyl, 2-benzoxazolyl or benzothiazolyl or, as radicals of partially hydrogenated or completely hydrogenated heterocyclic rings, for example also dihydropyridinyl, pyrrolidinyl, for example 2- or 3-(N-methylpyrrolidinyl), piperazinyl, morpholinyl, thiomorpholinyl, tetrahydrothienyl, benzodioxolanyl.

Physiologically tolerable salts of the compounds of the formula I are, in particular, pharmaceutically utilizable or nontoxic salts.

Such salts are formed, for example, from compounds of the formula I which contain acidic groups, for example carboxyl, with alkali metals or alkaline earth metals, such as, for example, Na, K, Mg and Ca, and also with physiologically tolerable organic amines, such as, for example, triethylamine, ethanolamine or tris(2-hydroxyethyl)amine.

Compounds of the formula I which contain basic groups, for example an amino group or a guanidino group, form salts with inorganic acids, such as, for example, hydrochloric acid, sulfuric acid or phosphoric acid, and with organic carboxylic or sulfonic acids, such as, for example, acetic acid, citric acid, benzoic acid, maleic acid, fumaric acid, tartaric acid, methanesulfonic acid or p-toluenesulfonic acid.

If the compounds of the formula I contain one or more centers of asymmetry, these can independently of one another have the S configuration or the R configuration. The invention includes all possible stereoisomers, for example enantiomers and diastereomers, and mixtures of two or more stereoisomeric forms, for example mixtures of enantiomers and/or diastereomers, in all ratios. The invention thus relates to enantiomers in enantiomerically pure form, both as levo- and as dextrorotatory antipodes. in the form of racemates and in the form of mixtures of the two enantiomers in all ratios. If cis/trans isomerism is present, the invention relates to both the cis form and the trans form and mixtures of these forms.

The present invention also relates to all these tautomers. The present invention furthermore includes all solvates of compounds of the formula I, for example hydrates or adducts with alcohols, as well as derivatives of the compounds of the formula I, for example esters, prodrugs and metabolites which act like the compounds of the formula I.

Generally, compounds of the formula I are preferred which have a uniform configuration at chiral centers, e.g. at the chiral carbon atom representing D and at the center W in the 5-membered ring heterocycle in the formula I.

The compounds of the formula I can be prepared, for example, by fragment condensation of a compound of the formula II

with a compound of the formula III,

where W, Y, Z, B, D, E, R and b, d, e, f, g, and h are defined as indicated above and G is hydroxycarbonyl, (C₁-C₆)-alkoxycarbonyl, activated carboxylic acid derivatives, such as acid chlorides or active esters, or isocyanato.

For the condensation of the compounds of the formula II with those of the formula III, the coupling methods of peptide chemistry known per se (see, for example, Houben-Weyl, Methoden der Organischen Chemie [Methods of organic chemistry], Volume 15/1 and 15/2, Georg Thieme Verlag, Stuttgart, 1974) are advantageously used. To do this, as a rule it is necessary that nonreacting amino groups present are protected by reversible protective groups during the condensation. The same applies to carboxyl groups not participating in the reaction, which are preferably present as (C₁-C₆)-alkyl, benzyl or tert-butyl esters. Amino group protection is unnecessary if the amino groups to be generated are still present as nitro or cyano groups and are formed, for example, by hydrogenation only after the coupling. After the coupling, the protective groups present are removed in a suitable manner. For example, NO₂ groups (guanidino protection), benzyloxycarbonyl groups and benzyl esters can be removed by hydrogenation. The protective groups of the tert-butyl type are removed under acidic conditions. while the 9-fluorenylmethyloxycarbonyl radical is removed by secondary amines. The compounds of the formula I can also be prepared, for example, by synthesizing the compounds stepwise on a solid phase according to customary methods, as is illustrated by way of example below.

Compounds of the formula II in which W is R¹—A—C(R¹³), Y is a carbonyl group and Z is NR⁰ can be prepared, for example, by first reacting compounds of the formula IV

in a Bucherer reaction to give compounds of the formula V,

in which just as in the formula IV R¹, R¹³ and A are defined as indicated above (H. T. Bucherer, V. A. Lieb. J. Prakt. Chem. 141(1934), 5). Compounds of the formula VI,

in which R¹, R¹³, A, B and G are defined as indicated above can then be obtained by first reacting the compounds of the formula V, for example, with an alkylating reagent which introduces the radical —B—G into the molecule. The reaction of compounds of the formula VI with a second reagent of the formula R⁰—LG, in which R⁰ has the meanings indicated above and LG is a nucleophilically substitutable leaving group, for example halogen, in particular chlorine or bromine. (C₁-C₄)-alkoxy, optionally substituted phenoxy or a heterocyclic leaving group such as, for example, imidazolyl, leads to the corresponding compounds of the formula II. These reactions can be carried out analogously to known methods familiar to the person skilled in the art. Depending on the individual case, it may be appropriate here, as in all steps in the synthesis of the compounds of the formula I, temporarily to block functional groups which could lead to side reactions or undesired reactions by means of a protective group strategy adapted to the synthesis problem, what is known to the person skilled in the art.

If W is R¹—A—CH═C, this structural element can be introduced, for example, by condensing an aldehyde with a 5-membered ring heterocycle which contains a methylene group in the position corresponding to the group W analogously to known methods.

Compounds of the formula I in which the 5-membered ring heterocycle is a dioxo- or thioxo-oxo-substituted imidazolidine ring in which W is R¹—A—C(R¹³) can also be obtained as follows:

By reaction of α-amino acids or N-substituted α-amino acids or preferably their esters, for example the methyl, ethyl, tert-butyl or benzyl esters, for example of a compound of the formula VII,

in which R⁰, R¹, R¹³ and A are defined as indicated above, with an isocyanate or isothiocyanate, for example, of the formula VIII,

in which B, D, E and R and also b, c, d, e, f, g and h are defined as indicated above and U is isocyanato or isothiocyanato, there are obtained urea or thiourea derivatives, for example of the formula IX

for which the definitions indicated above apply and in which V is oxygen or sulfur, and which by heating with acid are cyclized with hydrolysis of the ester functions to give compounds of the formula Ia

in which V is oxygen or sulfur, W is R¹—A—C(R¹³) and for which otherwise the meanings indicated above apply. The cyclization of the compounds of the formula IX to the compounds of the formula Ia can also be carried out by treatment with bases in inert solvents, for example by treatment with sodium hydride in an aprotic solvent such as dimethylformamide.

During the cyclization, guanidino groups can be blocked by protective groups, for example NO₂. Amino groups can be present in protected form or still as an NO₂ or cyano function which can later be reduced to the amino group or, in the case of the cyano group, also be converted into the formamidino group.

Compounds of the formula I in which the 5-membered ring heterocycle is a dioxo- or thioxo-oxo-substituted imidazolidine ring in which W is R¹—A—C(R¹³) and c is 1 can also be obtained by reacting a compound of the formula VII with an isocyanate or isothiocyanate of the formula X

in which B, U and b are defined as indicated above for the formula VIII and Q is an alkoxy group, for example a (C₁-C₄)-alkoxy group such as methoxy, ethoxy or tert-butoxy, a (C₆-C₁₄)-aryloxy group, for example phenoxy, or a (C₆-C₁₄)-aryl-(C₁-C₄)-alkoxy group, for example benzyloxy. In this case, a compound of the formula XI

is obtained in which A, B, V, Q, R⁰, R¹, R¹³ and b are defined as indicated above for the formulae IX and X, which is then cyclized under the influence of an acid or of a base, such as described above for the cyclization of the compounds of the formula IX, to a compound of the formula XII

in which B, Q, V, W, R⁰ and b are defined as indicated above for the formulae Ia and X. From the compound of the formula XII, a compound of the formula Ia is then obtained by hydrolysis of the group CO—Q to give the carboxylic acid COOH and subsequent coupling with a compound of the formula III, as described above for the coupling of the compounds of the formulae II and III. Here too, during the cyclization functional groups can be present in protected form or in the form of precursors, for example guanidino groups can be blocked by NO₂ or amino groups can be present in protected form or still as an NO₂ or cyano function which can later be reduced to the amino group or, in the case of the cyano group, also be converted into the formamidino group.

A further method for the preparation of compounds of the formula Ia is, for example, the reaction of compounds of the formula XIII,

in which W is R¹—A—C(R¹³) and for which otherwise the definitions indicated above apply, with phosgene, thiophosgene or corresponding equivalents (analogously to S. Goldschmidt and M. Wick, Liebigs Ann. Chem. 575 (1952), 217-231 and C. Tropp, Chem. Ber. 61 (1928), 1431-1439).

A conversion of an amino function into a guanidino function can be carried out using the following reagents:

1. O-Methylisourea (S. Weiss and H. Krommer, Chemiker Zeitung 98 (1974), 617-618)

2. S-Methylisothiourea (R. F. Borne, M. L. Forrester and I. W. Waters, J. Med. Chem. 20 (1977), 771-776)

3. Nitro-S-methylisothiourea (L. S. Hafner and R. E. Evans, J. Org. Chem. 24 (1959) 57)

4. Formamidinosulfonic acid (K. Kim, Y.-T. Lin and H. S. Mosher, Tetrah. Lett. 29 (1988), 3183-3186)

5. 3,5-Dimethyl-1-pyrazolylformamidinium nitrate (F. L. Scott, D. G. O'Donovan and J. Reilly, J. Amer. Chem. Soc. 75 (1953), 4053-4054)

6. N,N′-Di-tert-butyloxycarbonyl-S-methylisothiourea (R. J. Bergeron and J. S. McManis, J. Org. Chem. 52 (1987), 1700-1703)

7. N-Alkoxycarbonyl-, N,N′-dialkoxycarbonyl-, N-alkylcarbonyl- and N,N′-dialkylcarbonyl-S-methylisothiourea (H. Wollweber, H. Kölling, E. Niemers, A. Widdig, P. Andrews, H.-P. Schulz and H. Thomas, Arzneim. Forsch./Drug Res. 34 (1984), 531-542).

Amides can be obtained, for example, from the corresponding nitrites (cyano compounds) according to methods known from the literature, for example by partial hydrolysis under acidic or basic conditions.

With respect to the preparation of the compounds of the formula I, the disclosure of the following documents is fully incorporated by reference: WO-A-95/14008, German Patent Application 19635522.2 and the Patent Applications corresponding to it, for example European Patent Application 97103712.2 and U.S. patent aplication Ser. No. 08/821,253, as well as WO-A-96/33976.

The compounds of the formula I are antagonists of the adhesion receptor VLA-4. They have the ability to inhibit cell-cell and cell-matrix interaction processes in which interactions between VLA-4 and its ligands play a part. The activity of the compounds of the formula I can be demonstrated, for example, in an assay in which the binding of cells which contain the VLA-4 receptor, for example leucocytes, to ligands of this receptor is measured, for example to VCAM-1, which for this purpose can advantageously also be prepared by genetic engineering. Details of such an assay are described below. In particular, the compounds of the formula I are able to inhibit the adhesion and the migration of leucocytes, for example the adhesion of leucocytes to endothelial cells which—as explained above—is controlled via the VCAM-1/VLA-4-adhesion mechanism.

The compounds of the formula I and their physiologically tolerable salts are therefore suitable for the treatment and prophylaxis of diseases which are based on the interaction between the VLA-4 receptor and its ligands or can be influenced by inhibition of this interaction, and in particular they are suitable for the treatment and prophylaxis of diseases which are caused at least partially by an undesired extent of leucocyte adhesion and/or leucocyte migration or are associated therewith, and for whose prevention, alleviation or cure the adhesion and/or migration of leucocytes should be decreased. They can thus be employed, for example, as antiinflammatory agents in the case of inflammatory symptoms having very different causes. The compounds of the formula I according to the present invention are used, for example, for the treatment or prophylaxis of rheumatoid arthritis, inflammatory bowel disease (ulcerative colitis), systemic lupus erythematosus or for the treatment or prophylaxis of inflammatory disorders of the central nervous system, such as, for example, multiple sclerosis, for the treatment or prophylaxis of asthma or of allergies. for example allergies of the delayed type (type IV allergy), furthermore for the treatment or prophylaxis of cardiovascular disorders, arteriosclerosis, restenosis, for the treatment or prophylaxis of diabetes, for the prevention of damage to organ transplants, for the inhibition of tumor growth or tumor metastasis in various malignancies, for the therapy of malaria, and also of other diseases in which blocking of the integrin VLA-4 and/or influencing of the leucocyte activity appears appropriate for prevention, alleviation or cure. The compounds of the formula I and their salts can furthermore be employed for diagnostic purposes, e.g. in in vitro diagnoses, and as tools in biochemical investigations in which VLA-4 blocking or influencing of cell—cell or cell-matrix interactions is intended.

The compounds of the formula I and their physiologically tolerable salts can be administered according to the invention, as pharmaceuticals for therapy or prophylaxis, to animals, preferably to mammals, and in particular to man. They can be administered per se, in mixtures with one another or in the form of pharmaceutical preparations which permit enteral or parenteral use and which as active constituent contain an efficacious dose of at least one compound of the formula I and/or its physiologically tolerable salts in addition to customary, pharmaceutically innocuous excipients and/or additives. The present invention also relates to the use of pharmaceutical preparations which contain one or more compounds of the formula I and/or their physiologically tolerable salts for the abovementioned inventive uses of the compounds of the formula I. The pharmaceutical preparations normally contain approximately 0.5 to 90% by weight of the therapeutically active compounds of the formula I and/or their physiologically tolerable salts.

The pharmaceuticals can be administered orally, for example in the form of pills, tablets, filn-coated tablets, sugar-coated tablets, granules, hard and soft gelatin capsules, solutions, syrups, emulsions or suspensions. However, administration can also take place rectally, for example in the form of suppositories, or parenterally, for example in the form of injection or infusion solutions, microcapsules or rods, or percutaneously, for example in the form of ointments or tinctures, or by other routes, for example in the form of nasal sprays or aerosol mixtures.

The pharmaceutical preparations to be employed according to the invention are prepared in a manner known per se, pharmaceutically inert inorganic and/or organic excipients being used in addition to the compound(s) of the formula I and/or its/their physiologically tolerable salts. For the production of pills, tablets, sugar-coated tablets and hard gelatin capsules, it is possible to use, for example, lactose, corn starch or derivatives thereof, talc, stearic acid or its salts, etc. Excipients for soft gelatin capsules and suppositories are, for example, fats, waxes, semisolid and liquid polyols, natural or hardened oils, etc. Suitable excipients for the preparation of solutions, for example injection solutions, or of emulsions or syrups are, for example, water, alcohols, glycerol, polyols, sucrose, invert sugar, glucose, vegetable oils, etc. Suitable excipients for microcapsules, implants or rods are, for example, copolymers of glycolic acid and lactic acid.

In addition to the active compounds and excipients the pharmaceutical preparations can additionally contain additives, such as, for example, fillers, disintegrants, binders, lubricants, wetting agents, stabilizers, emulsifiers, preservatives, sweeteners, colorants, flavorings or aromatizers, thickeners, diluents, buffer substances, and also solvents or solubilizers or agents for achieving a depot effect, as well as salts for changing the osmotic pressure, coatings or antioxidants. They can also contain two or more compounds of the formula I and/or their physiologically tolerable salts. In addition to at least one compound of the formula I and/or its physiologically tolerable salts, they can further contain one or more other therapeutically or prophylactically active substances, for example substances having antiinflammatory action.

The dose can vary within wide limits and is to be adapted to the individual conditions in each individual case. In general, in the case of oral administration a daily dose of approximately 0.01 to 100 mg/kg, preferably 0.1 to 10 mg/kg, in particular 0.3 to 2 mg/kg of body weight is adequate to achieve effective results. In the case of intravenous admninistration, the daily dose is in general approximately 0.01 to 50 mg/kg, preferably 0.01 to 10 mg/kg of body weight. The daily dose can be subdivided, in particular in the case of administration of relatively large amounts, into a number of, for example 2, 3 or 4, part administrations. Where appropriate, it may be necessary, depending on individual behavior, to deviate upwards or downwards from the indicated daily dose. Pharmaceutical preparations normally contain 0.2 to 500 mg, preferably 1 to 100 mg, of active compound of the formula I and/or its physiologically tolerable salts per dose.

Certain compounds of the formula I have not been explicitly disclosed in the prior art and represent a selection of the variety of compounds covered by the German Patent Application 19635522.2 and the Patent Applications corresponding to it. The present invention also relates to these novel compounds per se. The present invention thus also relates to compounds of the formula Ib per se,

e, g and h independently of one another are 0, 1, 2, 3, 4, 5 or 6;

in all their stereoisomeric forms and mixtures thereof in any ratio, and their physiologically tolerable salts.

All the above explanations for the formula I, for example with respect to alkyl radicals, aryl radicals, etc., also apply to the compounds of the formula Ic correspondingly. The above preferred meanings also apply here correspondingly. In addition, particularly preferably, in the compounds of the formula Ic, independently of one another, b is 1, c is 1, d is 1, f is 0 and g is 0. e and h are particularly preferably independently of one another 0 or 1.

The above explanations for the preparation of the compounds of the formula I and their use likewise also apply to the compounds of the formula Ic. These compounds, of course, are also inhibitors of leucocyte adhesion and/or antagonists of the VLA-4 receptor and are suitable for the treatment and prophylaxis of diseases which are caused by an undesired extent of leucocyte adhesion and/or leucocyte migration or which are associated therewith or in which cell—cell or cell-matrix interactions which are based on interactions of VLA-4 receptors with their ligands play a part, for example of inflammatory processes. The present invention furthermore relates to the compounds of the formula Ic for use as pharmaceuticals and to pharmaceutical preparations which contain one or more compounds of the formula Ic and/or their physiologically tolerable salts in addition to pharmaceutically innocuous excipients and/or additives.

Furthermore, in the prior art still no compounds of the formula I are disclosed in which b is 1 and B is a substituted alkylene radical. The present invention thus also relates to those compounds of the formula Id per se,

e, g and h independently of one another are 0, 1, 2, 3, 4, 5 or 6;

in all their stereoisomeric forms and mixtures thereof in any ratio, and their physiologically tolerable salts.

All above explanations for the formula I, for example with respect to alkyl radicals, aryl radicals, etc. also apply to the compounds of the formula Id correspondingly. The above preferred meanings also apply here correspondingly. In addition, particularly preferably, in the compounds of the formula Id, independently of one another, c is 1, d is 1, f is 0 and g is 0. e and h are particularly preferably independently of one another 0 or 1. It is also particularly preferred if Y is a carbonyl group. With respect to the group B, in addition the following applies to the compounds of the formula Id.

The (C₁-C₆)-alkylene radical representing the group B in the compounds of the formula Id is preferably a (C₁-C₄)-alkylene radical, particularly preferably a methylene radical or an ethylene radical (=1,2-ethylene), very particularly preferably a methylene radical. The substituent on the group B can on the one hand contain a cyclic system when it is a substituent from the group consisting of (C₃-C₁₀)-cycloalkyl, (C₃-C₁₀)-cycloalkyl-(C₁-C₁₀)-alkyl, optionally substituted (C₆-C₁₄)-aryl, (C₆-C₁₄)-aryl-(C₁-C₆)-alkyl optionally substituded in the aryl radical, optionally substituted heteroaryl and heteroaryl-(C₁-C₆)-alkyl optionally substituted in the heteroaryl radical, and can on the other hand be acyclic when it is a substituent from the group consisting of (C₁-C₈)-alkyl, (C₂-C₈)-alkenyl and (C₂-C₈)-alkynyl. These acyclic substituents can each contain 2, 3, 4, 5, 6, 7 or 8 carbon atoms or, in the case of the saturated alkyl radical, also 1 carbon atom. In the case of the alkenyl radicals and alkynyl radicals, the double bond or triple bond can be located in any desired position and in the case of the double bond can have the cis configuration or trans configuration. As explained above, these alkyl radicals, alkenyl radicals and alkynyl radicals can be straight-chain or branched.

As examples of substituents which the (C₁-C₆)-alkylene radical representing B can carry the following are mentioned: methyl, ethyl, n-propyl, n-butyl, n-pentyl, n-hexyl, n-heptyl, n-octyl, isopropyl, isobutyl, isopentyl, isohexyl, sec-butyl, tert-butyl, tert-pentyl, neopentyl, neohexyl, 3-methylpentyl, 2-ethylbutyl, vinyl, alkyl, 1-propenyl, 2-butenyl, 3-butenyl, 3-methyl-2-butenyl, ethynyl, 1-propynyl, 2-propynyl, 6-hexynyl, phenyl, benzyl, 1-phenylethyl, 2-phenylethyl, 3-phenylpropyl, 4-biphenylylmethyl, cyclopropyl, cyclopropylmethyl, cyclopentyl, cyclohexyl, cyclohexylmethyl, 2-cyclohexylethyl, 3-cyclooctylpropyl, 2-pyridyl, 3-pyridyl, 4-pyridyl, 4-pyridylmethyl, 2-(4-pyridyl)ethyl, 2-furylmethyl, 2-thienylmethyl, 3-thienylmethyl or 2-(3-Indolyl)ethyl. Preferably, the substituent which the (C₁-C₆)-alkylene radical representing B can carry, is a (C₁-C₈)-alkyl radical.

Preferred compounds of the formula Id are those in which simultaneously

W is R¹—A—C(R¹³);

Example 4 Solid-phase Synthesis (General Procedure)

General

The syntheses on the polymeric support were carried out according to the synthesis sequence which is shown in Scheme 1. The radicals R⁵⁰ to R⁵⁵ in Scheme 1 have the meaning of the radicals which are located in the position in the molecule concerned in formula I, or they can contain functional groups in protected form or in the form of precursors. R⁵⁰ corresponds to the radical R. R⁵¹ corresponds to the radicals R⁴ and R¹⁵, where functional groups present in these radicals can be present in protected form or in the form of precursors (the radical —NHR⁵¹ can thus represent, for example, the radical of an amino acid which is formally obtained by removing a hydrogen atom from the amino group). R⁵², together with the CH group to which this radical is bonded, corresponds to the group B (R⁵² thus corresponds to a substituent on a methylene group representing B). R⁵³ corresponds to R¹³. R⁵⁴ corresponds to the group R¹—A, where functional groups present therein can be present in protected form or in the form of precursors R⁵⁵ corresponds to the group R⁰.

The synthesis of intermediates on a larger scale was carried out in special reaction vessels with frits inserted at the bottom of the reaction vessel; the synthesis of the compounds of the formula I was carried out in syringes or reaction blocks (Act 496, MultiSynTech). The syntheses on the resin were monitored by on bead analysis (FT-IR with ATR unit and MAS-NMR) and cleavage of an analytical sample from the resin (HPLC, MS, NMR).

Preparation of the Aspartic Acid Building Block FmocAsp(OH)-OAllyl

FmocAsp(OtBu)OAllyl (40 g, 88.7 mmol) was treated with 25 ml of trifluoroacetic acid and the mixture was stirred at room temperature for 30 min. The solvent was stripped off on a rotary evaporator. The residue was dried in vacuo. FmocAsp(OH)OAllyl was obtained as a yellow oil (33.9 g, 97%).

ES(+)-MS: 395.2 (M+H)⁺.

Linkage to the Polymeric Support (Step A in Scheme 1)

40 g of Wang polystyrene resin (1.1 mmol/g; Bachem) were preswollen at room temperature with 20 ml of DMF for 5 min. After addition of a solution of 26.0 g (1.5 equivalents) of FmocAsp(OH)OAllyl and 34.3 g (1.5 equivalents) of 1-benzotriazolyloxytripyrrolidinophosphonium hexafluorophosphate in (PyBOP) and 9.3 ml (1.5 equivalents) of diisopropylethylainine in 120 ml of DMF, the mixture was shaken at 40° C. for 10 h. After reaction was complete, the solution was filtered off with suction and the resin was washed with DMF (5×20 ml). After addition of a solution of acetic anhydride (10 ml) and diisopropylethylamine (9.3 ml, 1.5 equivalents) in 40 ml of DMF, the mixture was again shaken at room temperature for 30 min. The solution was filtered off with suction and the resin was washed in succession three times each with 40 ml of DMF, of methanol and of dichloromethane. The resin was then dried in vacuo. Determination of the loading by the Fmoc method showed a loading of 0.6 mmol/g.

Cleavage of the Alkyl Group on the Polymeric Support (Step B)

The resin was preswollen under argon for 5 min in DMF at room temperature. After addition of tetrakis(triphenylphosphine)palladium and N-methylpyrrolidine (10 equivalents), the mixture was shaken at 40° C. for 6 h under argon. After reaction was complete, the solution was filtered off with suction and the resin was washed in succession three times each with DMF, methanol, toluene and dichloromethane and then dried.

Coupling with Amino Compounds on the Polymeric Support (Step C)

The loaded resin with a free carboxyl function was preswollen at room temperature for 5 min in DMF. After addition of a solution of HOBt (1.2 equivalents), TOTU (1.2 equivalents) and diisopropylethylainine (1.2 equivalents) in DMF, the mixture was shaken at room temperature for 30 min. The amino compound (1.2 equivalents) was added dissolved in DMF. The suspension was shaken at room temperature until reaction was complete (HPLC checking). After reaction was complete, the solution was filtered off with suction and the resin was washed in succession three times each with DMF, methanol, toluene and dichloromethane and then dried.

Cleavage of the Fmoc Protective Group (Step D)

For cleavage of the Fmoc protective group, the resin was preswollen at room temperature for 5 min in DMF. After addition of a solution of DMF/piperidine (1/1), the mixture was shaken at room temperature for 20 min. The solution was filtered off with suction and the process was repeated. The cleavage of an analytical sample showed complete reaction according to HPLC/MS investigation. After complete reaction, the resin was washed three times with dichloromethane and employed directly in the coupling.

Coupling with α-Halocarboxylic Acids (Step E)

The resin was preswollen for 5 min with dichloromethane at room temperature. The α-halocarboxylic acid halides (1.5 equivalents) were added dissolved in dichloromethane. After addition of a catalytic amount of 4-dimethylaminopyridine and diisopropylethylamine (1 equivalent), the mixture was shaken at room temperature for 8 h. After reaction was complete, the solution was filtered off with suction and the resin was washed in succession three times each with DMF, toluene and dichloromethane and then immediately further reacted.

Instead of using the acid halides, the coupling can also be carried out using the acids and diisopropylcarbodiimide (DIC). For this, the symmetrical anhydrides are formed from α-halocarboxylic acids (5 equivalents) by 30-minute reaction with dilsopropylcarbodiimide (2.4 equivalents) in dichloromethane. After this time, 2 equivalents of diisopropylethylamine are added. The mixture is added to the resin and shaken at room temperature for 12 h. After reaction is complete, the solution is filtered off with suction and the resin is washed in succession three times each with DMF, toluene and dichloromethane and then immediately further reacted.

Coupling of the α-Haloacyl Compounds with Hydantoins (Step F)

The 4,4-disubstituted hydantoins (2 equivalents) were activated in DMF with diazabicycloundecene (DBU) (2 equivalents) at room temperature. The activated solution was added after 15 min to the resin preswollen in DMF for 5 min. The mixture was shaken at room temperature for 8 h. After reaction was complete, the solution was filtered off with suction and the resin was washed in succession three times each with DMF, methanol, toluene and dichloromethane and then dried.

N-Alkylation of the Hydantoin on the Polymeric Support (Step G)

The resin was preswollen for 5 min in DMF at room temperature. After addition of N′″-tert-butyl-N,N,N,N′,N″,N″-hexamethylphosphorimidic triamide (phosphazene base Pl-t-Bu) (3 equivalents), the mixture was shaken at room temperature for 30 min. After addition of the alkylating agent (bromide or iodide), the mixture was shaken at room temperature for 4 h. After reaction was complete, the solution was filtered off with suction and the resin was washed in succession three times each with DMF, toluene and dichloromethane and then dried.

Instead of using phosphazenes, the alkylation can also be carried out using cesium carbonate. For this, the resin is preswollen for 5 min in DMF at room temperature. After addition of cesium carbonate (3 equivalents), the mixture is shaken at room temperature for 30 min. After addition of the alkylating agent (bromide or iodide), the mixture is shaken at 50° C. for 6 h.

After reaction is complete, the solution is filtered off with suction and the resin is washed in succession three times each with DMF, methanol/water/DMF (1.5/1.5/7), DMF, toluene and dichloromethane and then dried.

Cleavage from the Resin (Step H)

For cleavage of the compound from the resin, a mixture of trifluoroacetic acid/dichloromethane (1/1) was added to the resin. The suspension was shaken for 1 h. The resin was filtered off. The renaming solution was concentrated in vacuo. The residue was purified by silica gel chromatography (dichloromethane and ethyl acetate).

Investigation of the Biological Activity

As a test method for the activity of the compounds of the formula I on the interaction between VCAM-1 and VLA-4, an assay is used which is specific for this interaction. The cellular binding components, i.e. the VLA-4-integrins, are offered in their natural form as surface molecules on human U937 cells (ATCC CRL 1593), which belong to the group of leucocytes. As specific binding components, recombinant soluble fusion proteins, prepared by genetic engineering and consisting of the extracytoplasmic domains of human VCAM-1 and the constant region of a human immunoglobulin of the subclass IgG1, are used.

Test Method

Assay for the Measurement of the Adhesion of U937 Cells (ATCC CRL 1593) to hVCAM-1(1-3)-IgG

1. Preparation of Human VCAM-1(1-3)-IgG and Human CD4-IgG

A genetic construct for the expression of the extracellular domains of human VCAM-1 was employed, associated with the genetic sequence of the heavy chain of human immunoglobulin IgG1 (hinge, CH2 and CH3 regions), from Dr. Brian Seed, Massachusetts General Hospital, Boston, USA. The soluble fusion protein hVCAM-1(1-3)-IgG contained the throe amino-terminal extracellular immunoglobulin-like domains of human VCAM-1 (Damle and Aruffo, Proc. Natl. Acad. Sci. USA 1991, 88, 6403). CD4-IgG (Zettlmeissl et al., DNA and Cell Biology 1990, 9, 347) served as a fusion protein for negative controls. The recombinant proteins were expressed as soluble proteins after DEAE/dextran-mediated DNA-transfection in COS cells (ATCC CRL1651) according to standard procedures (Ausubel et al., Current protocols in molecular biology, John Wiley & Sons, Inc., 1994).

2. Assay for the Measurement of the Adhesion of U937 Cells to hVCAM-1(1-3)-IgG

2.1 96-well microtiter test plates (Nunc Maxisorb) were incubated at room temperature for 1 hour with 100 μl/well of a goat-anti-human IgG antibody solution (10 μg/ml in 50 mM Tris, pH 9.5). After removing the antibody solution, washing was carried out once with PBS.

2.2 150 μl/well of a blocking buffer (1% BSA in PBS) was incubated on the plates at room temperature for 0.5 hour. After removing the blocking buffer, washing was carried out once with PBS.

2.3 100 μl per well of a cell culture supernatant of transfected COS cells were incubated on the plates at room temperature for 1.5 hours. The COS cells were transfected with a plasmid which codes for the three N-terminal immunoglobulin-like domains of VCAM-1, coupled to the Fc part of human IgG₁ (hVCAM-1(1-3)-IgG). The content of hVCAM-1(1-3)-IgG was about 0.5-1 μg/ml. After removing the culture supernatant, washing was carried out once with PBS.

2.4 The plates were incubated at room temperature for 20 minutes with 100 μl/well of Fc receptor blocking buffer (1 mg/ml of γ-globulin, 100 mM NaCl, 100 μM MgCl₂, 100 μM MnCl₂, 100 μM CaCl₂, 1 mg/ml BSA in 50 mM HEPES, pH 7.5). After removing the Fc receptor blocking buffer, washing was carried out once with PBS.

2.5 20 μl of binding buffer (100 mM NaCl₂, 100 μM MgCl₂, 100 μM CaCl₂, 1 mg/ml BSA in 50 mM HEPES, pH 7.5), were initially introduced, the substances to be tested were added in 10 μl of binding buffer and the mixture was incubated for 20 minutes. As controls, antibodies against VCAM-1 (BBT, No. BBA6) and against VLA-4 (Immunotech, No. 0764) were used.

2.6 U937 cells were incubated in Fc receptor blocking buffer for 20 minutes and then pipetted in at a concentration of 1×10⁶/ml and in an amount of 100 μl per well (final volume 125 μl/well).

2.7 The plates were slowly immersed at an angle of 45° in stop buffer (100 mM NaCl, 100 μM MgCl₂, 100 μM MnCl₂, 100 μM CaCl₂ in 25 mM Tris, pH 7.5) and shaken off. The process was repeated.

2.8 50 μl/well of a dye solution (16.7 μg/ml of Hoechst dye 33258, 4% formaldehyde, 0.5% Triton X-100 in PBS) were then incubated on the plates for 15 minutes.

2.9 The plates were shaken off and slowly immersed at an angle of 45° in stop buffer (100 mM NaCl, 100 μM MgCl₂, 100 μM MnCl₂, 100 μM CaCl₂ in 25 mM tris, pH 7.5). The process was repeated. Then, with the liquid, measurements were made in a cytofluorimeter (Millipore) (sensitivity: 5; filter: excitation wavelength: 360 nm, emission wavelength: 460 nm).

The intensity of the light emitted by the stained U937 cells is a measure of the number of the U937 cells adhered to the hVCAM-1(1-3)-IgG and remaining on the plate and thus a measure of the ability of the added test substance to inhibit this adhesion. From the inhibition of the adhesion at various concentrations of the test substance, the concentration IC₅₀ which leads to an inhibition of the adhesion by 50% was calculated.

The following test results were obtained:
